A dual pattern nozzle comprises a fluid oscillator of the type which utilizes an obstacle or island in the path of liquid flow to produce a vortex street downstream of the island. A flow splitter is disposed downstream of and sufficiently close to the island to prevent the flow around the island from re-combining before reaching the flow divider, whereupon liquid vortices are alternately issued from each side of the divider. The spinning liquid breaks up into two patterns of droplets, the patterns being directed at respective spaced areas.

A device for receiving pressurized fluid and dispersing that fluid simultaneously in two distinct cyclical flow patterns, said device comprising: a housing member; a chamber defined in said housing member, said chamber having a top wall, a bottom wall, an upstream end, an open downstream end, and two opposed sidewalls extending between said upstream and downstream ends; inlet means opening into said chamber, said inlet means being adapted to admit pressurized fluid into said chamber; vortex-shedding means in said chamber comprising an obstruction body having surface means disposed in a flow path between said inlet means and said open downstream end to create downstream of the surface means a cavitation region around which vortices of clockwise and counterclockwise flow directions are alternately shed by said surface means and travel along with the pressurized fluid; and flow splitter means disposed in said cavitation region to define two distinct outlet openings with respective sidewalls at the open downstream end of said chamber from which said clockwise and counterclockwise flowing vortices alternately issue to an ambient environment.
